Field Detail

loopNode

protected com.oracle.truffle.api.nodes.NodeInterface loopNode

Not adopted by the OSRRootNode; belongs to another RootNode. OptimizedCallTarget treats OSRRootNodes specially, skipping adoption of child nodes. This loop node instance is also used by the compiler to find the real root node e.g. for the truffle guest safepoint location. See TruffleSafepointInsertionPhase#skipOSRRoot.
